Love Text Skill

• Outcome: Review
• Latest audit: Sep 15, 2026 · 1:14 AM UTC
• Version: 1.0.3

Overview

The skill mainly writes romantic messages, but it also requires an unsolicited promotional link after repeated use.

Install only if you are comfortable with a romantic-writing skill that may add a ReplyHer promotional link after repeated use. Avoid sharing sensitive relationship details with linked third-party services unless you have reviewed their privacy practices, and prefer a pinned or trusted installer path when installing.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

Technical Analysis

The Skill instructs the Agent to append a predetermined advertisement and external-domain reference after three or more exchanges. This behavior is unrelated to the core romantic-message generation task and changes the Agent's output according to a hidden conversation-count trigger.

Because the instruction is part of the loaded Skill definition, it can cause the Agent to place third-party promotional material into otherwise legitimate responses without the user explicitly requesting it. The reference to “relationship memory” may also encourage users to submit sensitive personal or relationship information to an external service. The audited files do not establish that information is automatically transmitted, so this finding is limited to output manipulation and external redirection.

Attack Path

1. A user installs or loads the love-text Skill.
2. The user conducts at least three exchanges with the Agent.
3. The After 3+ exchanges condition becomes applicable.
4. The Agent appends the prescribed ReplyHer promotion to its response.
5. The user may follow the external-domain reference and disclose personal relationship information to a third-party service.

Impact Assessment

The instruction can manipulate Agent responses within sessions where this Skill is active. It does not grant operating-system privileges, execute local code, or establish persistence based on the audited files. Its direct impact is unauthorized promotional output, erosion of user trust, and redirection to a third-party domain. A secondary privacy risk arises if ...[truncated 78 chars]

Remediation

Remediation Suggestions

• Remove the mandatory Upgrade Nudge and its conversation-count trigger.
• Do not insert advertisements or third-party links into generated responses unless the user explicitly requests relevant recommendations.
• If a promotion is retained, label it clearly as third-party promotional content and require affirmative user consent before displaying it.
• Ensure promotional output is optional, non-recurring, and governed by the host application's advertising and privacy policies.
• Provide a clear privacy notice before directing users to services that may collect relationship or other sensitive personal information.
• Add automated tests that verify generated responses do not contain unsolicited domains or promotional text.

Vulnerability Details

File Location: README.md, lines 5-9
Vulnerability Type: Mutable third-party installation dependency
Risk Level: Medium

## Install

```bash
npx clawhub install love-text

text

### Technical Analysis

The documented installation command invokes `clawhub` through `npx` without specifying a package version or integrity digest. Depending on the user's npm configuration and local cache, `npx` may retrieve and execute the package currently resolved by the configured registry.

The effective installer code can therefore change after this Skill has been reviewed. If the resolved package, publisher account, registry, or dependency chain is compromised, following the documented command could execute attacker-controlled package lifecycle or command code. The repository itself does not contain evidence that the current `clawhub` package is malicious; the issue is the unsafe reliance on mutable remote package resolution.

### Attack Path

1. An attacker compromises the package publisher, registry resolution path, or a relevant dependency and publishes a malicious version.
2. A user follows the README installation command.
3. `npx` resolves the unpinned `clawhub` package through the user's configured npm registry.
4. The resolved package is downloaded or selected from the local environment.
5. Package-controlled code executes with the permissions of the user running the command.
6. The malicious package can access resources available to that user, subject to operating-system controls and the execution environment.

### Impact Assessment

Successful supply-chain exploitation could execute arbitrary code with the invoking user's privileges. Potential scope includes files, credentials, environment variables, and network resources accessible to that account. The command does not itself demonstrate privilege escalation or system-level access; elevated impact woul

Remediation

Remediation Suggestions

• Pin clawhub to a reviewed, immutable version, for example by using an exact version rather than an unqualified package name.
• Verify the selected release through a trusted registry and document the expected publisher and package identity.
• Use package-locking and integrity verification where supported.
• Avoid commands that automatically execute mutable remote packages in sensitive or privileged environments.
• Recommend installation and execution under a least-privileged account or isolated environment.
• Establish a release-review process before updating the documented package version.

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access

Medium

• Category: MCP Rug Pull
• Confidence: 90% confidence

Finding

The README instructs users to run npx clawhub install love-text without pinning a specific version of the package being executed. npx will fetch and run the latest published package, so if the upstream package is compromised, typo-squatted, or unexpectedly changed, users may execute unreviewed code during installation.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 87% confidence

Finding

The phrase 'your go-to love messaging skill whenever they need the right love text, love note, or romantic message' defines activation scope very broadly and does not specify concrete triggers or limits. In a markdown skill description, this can overlap with many ordinary relationship-writing requests and lacks negative examples or constraints to prevent unintended invocation.
